Chisangalalo chachiwiri cha magwiridwe achiwiri mu mawonekedwe ambiri

Chiyambire kupezeka kwa zovuta zomwe sizili zachiwirizo mu 1960s, zapangitsa chidwi cha ofufuza, mpaka pano, malinga ndi zotsatirazi zachiwiri, zapanga kuchokera ku gulu la ultraviolet ku gulu lamalavu, olimbikitsidwa kwambiri kukula kwa laser,zamasoKugwiritsa ntchito chidziwitso, kaganizidwe kabwino kwambiri kwamalingaliro ndi minda ina. Malinga ndi osagwirizanaopticcNdipo lingaliro lolowera, ngakhale kusintha kwa ma sikolo kumagwirizana kwambiri ndi ma crystal symmetry, ndipo osagwirizana nawo si zero kokha mwa mitundu yopanda pake. Monga momwe ntchito yoyambira kwambiri yachiwiri imathandizira, mahule achiwiri amalepheretsa zaka zawo komanso kugwiritsa ntchito bwino mu quartz chiberekero chifukwa cha ma amorphous mawonekedwe ndi mawonekedwe a kusiyana pakati. Pakadali pano, njira zosinthira (polarication polarization, polarization polarization, magetsi oyendetsa bwino) amatha kuwononga mawonekedwe a mawonekedwe a zojambulajambula, komanso kusintha bwino kwa mawonekedwe achiwiri a fiber. Komabe, njirayi imafunikira zovuta komanso kukakamiza ukadaulo wokonzekera, ndipo imangokumana ndi gawo lofananira ndi gawo lofananira. Mphete yamiyendo yamiyendo yoyeserera yochokera ku Echo khoma limalepheretsa kukongola kwakukulu kwa ma hamonics achiwiri. Mwa kuswa mawonekedwe a mawonekedwe a njenjete, mawonekedwe achiwiri achinsinsi omwe ali ndi mawonekedwe apadera, koma amadalira pampu ya femptosecand kwambiri. Chifukwa chake, m'badwo wachiwiri wowongolera masinthidwe a Secticary ndi kusintha kwa kusintha kwa magwiridwe antchito ambiri, pompopompo popople, ndi mavuto ofunikira a sayansi ndi njira zambiri.

Gulu lofufuzira ku China lalimbikitsa Gallium Selenaum Gawo la Crystal gawo la micro-nano fiber. Pogwiritsa ntchito mwayi wamtundu wapamwamba kwambiri komanso kulamula kwa nthawi yayitali ku Grineum Aspicels, njira yolumikizirana ndi mitundu yambiri yolumikizirana, kupereka njira yatsopano yopititsira patsogolo njira zowonjezera ndi fibermagwero owala. Kututa koyenera kwa mitundu yachiwiri yogwirizana ndi kuchuluka kwa chiwembucho kumadalira gawo lachitatu: Nkhani Yaitali Kwambiri Kuwala Kwambiri Pakatikati Pakati pa GalliumMicro-Nano fiber, kuwongolera kwakukulu ndi dongosolo lalitali komanso dongosolo lalitali la gallium selelium selenial crystal, ndipo gawo lofananira ndi mawonekedwe a pafupipafupi komanso mobwerezabwereza.

Poyesera, fiber ya micro-nano yokonzedwa ndi makina owoneka bwino omwe ali ndi chizindikiritso chofanana ndi millimeter, yomwe imapereka kutalika kwakutali kwa kupukusa kwa kampu ndi mafunde achipongwe. Kutumiza kwachiwiri kwa gallium selenial ralstal kumapitilira 170 pm / v, komwe kumakhala kwakukulu kwambiri kuposa kuphatikizira kufinya kwa fiberi. Kuphatikiza apo, kapangidwe kambiri kwa gallium Selenal kumatsimikizira kufalitsa kwachiwiri kwa ma hamonics, kumapangitsa kusewera kwathunthu ndi mwayi wa kutalika kwa micro-nano fiber. Chofunika koposa, gawo lofananira pakati pa kupondaponda njira yopumira (he11) ndi njira yachiwiri yotsogola (eh11, he31, he31) imakhazikitsidwa ndi kuwongolera kukula kwa chipilala ndikukonzekera firro-nano fiber.

Malo omwe ali pamwambawa adayika maziko a njira yokwanira komanso yayikulu kwambiri ya ma harmonics achiwiri mu micro-nano fiber. Kuyesaku kumawonetsa kuti kutulutsa kwachiwiri ku Nanowatt kutheka pansi pa kampu ya 1550 NM Kupitilira apo, Kuwala kwa kapu kumakulitsidwa mpaka magawo atatu osintha a laser (1270/159/152, w1 + w2) amawonedwa panjira zisanu ndi chimodzi. Poika kuwala kwa kampu ndi daide yowala yowala (yosakhazikika) ndi bandwidth ya 79.3 nm, kogwirizana kwambiri ndi gulu lachiwiri lokhala ndi bandwidth ya 28.3 nm. Kuphatikiza apo, ngati mankhwala a Tear Extlogy angagwiritsidwe ntchito kulowetsa ukadaulo wosunthira kafukufukuyu, ndipo ochepa mabungwe a Gillium Seleks amatha kumera pamtunda wautali, njira yachiwiri yosinthira ikuyembekezeredwa.
